Referring to the drawings, the numeral l indicates the bowl of acentrifugal'separator,

:said bowl being of any'convent onal and approved construction atpresent in use. The feed-tube 2 enters the bowl 1 and is provided at itslower portion with the lateral outlets 3,

as is pustomary. The separating-bowl 1 is provided at its upper portionwith the "skimmed-milk outlet-passages Y 4 and the cream-outlet 5 abovethe passages 4.

Arranged within the body of the bowl 1 are, a plurality of coils 6 6 6*6, &c., arran ed in sets, said sets of coils being arrange onearator-bowl havingthe invention ap- Specification of Letters Patent. 1Patented March 13, 1906; Application filed April 14, 1905. strain.255,585.

The term coils as used herein isdesigned'as a broad or generic term applying to rings, coils, or similarparts arranged and combined in a manner herein specified foraccomplishing the functionsof the inven,

tion. In the preferred form of the invention the sets of'coils'6 6',&c., are arranged in spacedrelation and the various coils of each setare in'vertical alinement, so that vertical passages coils.

The number of sets. of

coils employed is immaterial, since such num-,.

ber may be varied according to the best results attained in the actualuse of the'niachine. The operation and advantages of the invention willnow be noted. .As the bowl 1 revolves in the customary manner the liquidtions of the liquid. However, it will be seen that thephir'ality ofpassages 2 will permit the cream-globules to separate at various points,and the coils of. the various sets of coils in the arrangement describedgreatly facilitate the separation. of the cream-globules', so that thelatter are free to rise in a manner which will .be apparent to those'versed in'this art.

'Figs.l2 and 4 illustrate a modification of the invention in which thelaterally-alined coils are arran ed in sets, (indicated at 10 1O 10 10,&c.',) t e sets being placed one above the other with the coils thereofin vertical and lateral alinement. The sets of coils 10 10*, &c.,howeverfare preferably made of conical form, the materialfrom which theyare constructed being wound helically instead of spirally, as indicatedin connection with the construction of Figs. 1- and 2.

p The coils of the sets 10 10*, &c., are secured to ether in anysuitable way, and the s aced re ation of the coilsof each set and of t esets of coils clined downwar is substantially the same as indicated withreference to the-preferred construction before described. Theform of thesets of coils 10 10, &c., is such that the passages 1*, Whichextend withthe (passages 8 inFig. 1, are inly instead of horizontally. The above isadvantageous .under certam conditions in separating the cream-globules Ifrom the milk, t

e liquid being forced downwardly instead of horizontally as it passesthrough the passages *8. The assagesv "F in Fig. 2 are the same as thosein icated at 7 in Fig. 1.

In a centrifugal cream-separator, the combination of aseparating-bowl, and spaced inner and outer coils in said bowl.

2. In a centrifugal cream-se arator, the combination of a aseparating-bow and spaced sets of inner and outer superposed coils-insaid bowl, the coils of each set being spaced from each other.

3.- In a centrifugal cream-separator, the combination of aseparating-bowl, and sets of inner and outer spaced coils in said bowl,the coils of each set being of approximately circular formation incross-section.

4. In a centrifugalcreamseparator, the combination of a separating-bowl,and sets of inner and outer coils in said bowl, the sets of coils beingso arranged as to form outflowpassages therebetween.

5. In a centrifugal cream-separator, the

combination of a separating-bowl, and sets of inner and outer coils insaid bowl, the sets of coils being so arran ed as to form verticaloutflow spaces there etween, the relative ositions of the coils of eachset being such'as 0 form lateral outflow spaces or passages.

6. In a centrifugal cream-separator, the combination of aseparating-bowl,- and sets of inner and outer coils in said bowl, thesets of coils being so arran ed as to form vertical outflow spaces thereetween, the relative positions of the. coils of each set with regard tothe coils of the next adjacentset, being such as to form straightlateral outflow-passages. q

7. In a centrifugal cream-separator, the combination of aseparating-bowl, .and sets 7 of inner and outer concentric spaced coilsin sald bowl.

8. In a centrifugal cream-separator. the combination of ,a 4 separatingbowl, sets of inner and outer concentric spaced coils in said bowl, anda-feed-tube entering the bowl centrally of the innermost set of coils.

:9. In a centrifugal cream-separator, the

combination of a separating-bowl, sets of coils in said bowl, andspacing means between the sets of coils.

10} In a centrifugal cream-separator, the combination of aseparatingbowl,-and sets of coils in said bowl, each set being made of asingle length of material.

11. In a centrifugal cream-separator, the combination of aseparating-bowl, sets' of coils disposed in the bowl, and barsconnecting the coils of each set.
